Mexico Oil Is Boon for Exxon to BP as Frontiers Teeter

Mexico’s vote on rules for the end of its 76-year state-oil monopoly couldn’t come at a better time for global energy companies from Exxon Mobil Corp. (XOM) to Royal Dutch Shell Plc.

With reserves holding $1.3 trillion of crude at yesterday’s prices, Mexico offers a new opportunity for deep-pocketed producers as well as pipeline and power companies to try and mimic an energy revolution that has spurred U.S. oil output to a 26-year high and pushed Canadian production to records. New access to Mexico comes amid unrest in some African oil nations and sanctions that threaten to strangle Russian output, places where some oil companies have invested heavily in production.
